PHP:post 全局变量的总长度是多少? [英] PHP: whats the total length of a post global variable?

问题描述

我想知道是否有人知道全局帖子的总长度.例如:

$_POST['formInput'] = "hello world，我能待多久?";

我正在创建一个站点，在该站点中，有人会在 textarea 中输入未知数量的字符，因此它可能是 word 文档中的 2 页.因此，如果有人知道除了使用 post global 之外我还可以如何做到这一点的任何其他方法?(它不能保存在文件中，因为它的重要数据我不想让其他人找到)这将非常有帮助.

谢谢

解决方案

检查您的 php.ini 中的 post_max_size.默认情况下，这通常约为 8mb，但如果您使用的是共享主机，则肯定会有所不同.

<预>;PHP 将接受的 POST 数据的最大大小.post_max_size = 8M

如果您希望向服务器发送大量数据，则必须使用 $_POST.为了进一步研究，我建议查看 POST Method Uploads 在文档中.

I was wondering if anybody knows the total length that a post global could be. e.g:

$_POST['formInput'] = "hello world, how long can i be?";

I am creating a site where someone will enter an unknown amount of chars into a textarea, so potentially it could be 2 pages on a word document. So if anybody knows of any other methods of how i can do this apart from using a post global? (it cant be saved in a file, as its important data that i dont want other people to find) That would be very helpful.

Thanks

Check your php.ini for post_max_size. This is typically about 8mb by default, but if you're on shared-hosting, it could definitely vary.

; Maximum size of POST data that PHP will accept.
post_max_size = 8M

You'll have to use $_POST if you wish to send large amounts of data to the server. For further study, I'd suggest checking out POST Method Uploads in the documentation.
